Buddy according to coin gecko 92% been mined in what? 16 years? what make you think that the last Bitcoin will be mined in 2140?
Because it is following a schedule. You can see the schedule here:
https://en.bitcoin.it/wiki/Controlled_supplyagain, Bitcoin has no real use at all it has no physical form nor backed by anything but the Fiat that people pay to get it.
perhaps will have a semi physical form once a country use it to pay it employs as part of the backed up will be in goods this country produce and the only country so far think of this is Nigeria and it's a poor country so this won't save Bitcoin.
It has real use, or at least it could have real use. Bitcoins can be exchanged for things other than fiat. Read this:

1-you agree that once people don't pay any fiat to get Bitcoin it will lose it value? meaning it's backed or semi backed by fiat
As long as people are willing to exchange things of value for bitcoins, then bitcoins will have value, regardless of what happens to fiat.
The problem with saying that something is "backed" or is not b"backed" is that the word "backed" is ambiguous. it means different things to different people. I suggest that when you say that Bitcoin is "semi-backed by fiat", you explain exactly what that means.
2-once the fiat that people pay lose it value Bitcoin will have the same or similar value to the fiat it been backed in?
If fiat loses value then everything else gains value with respect to that fiat. That is called inflation. Are you claiming that if you buy food with fiat and the value of the fiat goes to 0, then the value of food will go to 0 also?
3-Satoshi has a bigger plans than what we see or think and his plane will be executed once Bitcoin hit a huge price?
Other than the bitcoins that Satoshi may or may not control, Satoshi and any plan he might have are irrelevant at this point.
